"Modern science, as we know it today, is the daughter of the European Enlightenment. That age of intellectual ferment beginning in the early 18th century established “reason”, instead of divinely ordained revelation, as the basis of knowledge. At its core was the questioning of traditional institutions, morals, and customs which had previously upheld the supremacy of the church in the intellectual sphere, and feudal relations in the social sphere. In this intellectual atmosphere, science, the process of systematic pursuit of knowledge, underwent a huge qualitative change from its earlier reliance on scriptures and classical Greek authorities like Aristotle, into a methodology dependent on reason, critical questioning, and establishment of clear relationship between cause and effect by direct observation. As Rene Descartes, one of the intellectual giants of the Enlightenment, famously declared, and Karl Marx, probably the most complete intellectual offspring of the Enlightenment, adopted as his favourite motto, “de omnibus dubitandum”, that is, “Doubt everything”, became the reigning methodology of scientific enquiry."
